This is the first "MIB" to give the agents a whiz-bang modern car. The most modern vehicle previously was a "new hotness" 2003 Mercedes-Benz E550 in the 2002 sequel, but that was primarily a joke referring to the 1986 Ford LTD, referred to as a " Ford P.O.S.," in the first movie. The third film, which took place in the sixties, used a 1964 Ford Galaxie.
"MIB: International" includes a few throwbacks to the movies and the television series. The RC F goes airborne with the help of a big red button, just like that ' 86 LTD. A bigger and better hovercycle ties into the hovercycle from the TV show. The all-new move comes with a mid-seventies Jaguar XJ; whereas the first agents merely retrieved their weapons from the trunk, the XJ not only holds weapons, it disassembles into weapons systems.
As Jalopnik noted, in many ways this movie " looks just like 'Thor: Ragnarok' but set in a different universe." Should go well enough with a bucket of popcorn and pail of Coca-Cola, though.
